9b1d701af4 [CS] Add an option to block sensitive network specifier
Network specifiers are used for 2 purposes:

- As part of network requests to specify more information on the type
  of requested networks.
- On network agents to specify information about their networks.

The network specifiers of the requests and agents are matched to each
other. However, the agent network specifier may contain sensitive
information which we do not want forwarded to any app.

This CL adds an option to strip out this agent network specifier before
the network capabilities are forwarded to the app.

029d9ea119 Support strict mode private DNS on VPNs that provide Internet.
Currently, strict mode private DNS does not work on VPNs because
NetworkMonitor does not validate VPNs. When a VPN connects, it
immediately transitions to ValidatedState, skipping private DNS
hostname resolution.

This change makes NetworkMonitor perform private DNS hostname
resolution and evaluation even on VPNs.

In order to ensure that the system always immediately switches to
the VPN as soon as it connects, remove the unvalidated penalty
for VPN networks. This ensures that the VPN score is always 101
and the VPN always outscores other networks as soon as it
connects. Previously, it would only outscore other networks
when no-op validation completed.

Backport of 414b8c8b1c.

60cd85533d Add test coverage for strict mode private DNS.
Support faking out the DNS lookups used by NetworkMonitor to
resolve strict mode DNS, and add more test coverage.

These tests were partly adapted from tests we have in Q but
also contain new coverage. This is because in Q the interface
between ConnectivityService and NetworkMonitor changed
substantially, and it is impractical to backport
NetworkMonitorTest.

6a050c7c50 Revert "Update VPN capabilities when its underlying network set is null."
This reverts commit ad8805a6c2.

Bug: 126245192

Reason for revert: This change can lead to a deadlock that was fixed in http://ag/6580635. However, platform PMs think that fixing this is risky enough as this is not a recent problem and has been in the field for 3/4 of the year.

Note: The merged-in tag is used to avoid this change from getting merged into pi-dev-plus-aosp. This is to avoid merge conflicts since we mostly work in aosp/master which merges into pi-dev-plus-aosp.

47a6760c76 Remove ConnectivityManager and its usages from NetworkStatsService.
NSS needed it for getting VpnInfo[], NetworkState[] and
activeLinkProperties which it used to query via ConnectivityManager.

For VpnInfo[], this was racy as NSS may ignore intermediate changes to a
VPN's underlying networks. See http://b/123961098 for more context.

It may also lead to deadlocks b/w ConnectivityService and
NetworkStatsService. See http://b/126245192 for more info.

This change will ensure that NSS is never contending on any of
ConnectivityService locks.

This change also is cherry-picking cleanup made to NSS in
http://aosp/628368.

ad8805a6c2 Update VPN capabilities when its underlying network set is null.
Previously, they were only updated when underlying network set was
non-null.

This change also ensures that all the calls b/w ConnectivityService and
Vpn that leads to updating capabilities are on ConnectivityService
handler thread.

Additionally, it also ensures that capabilities are propagated after VPN
enters connected state.

This change also updates VPN capabilities inline from
ConnectivityService handler thread. Previously, there was an additional
loop where Vpn would update capabilities via NetworkAgent thru
AsyncChannel which posts back to CS handler thread, which could
potentially lead to delays in updating VPN capabilities.

4080a1bd15 Prefer default Internet network for upstream tethering.
Rather than use the crufty config.xml list of upstream transport types,
use ConnectivityService's notion of the default network for the upstream.
In cases where a DUN network is required and the default network is
currently a mobile network, look for a DUN network (code in Tethering
is currently responsible for requesting one).

80b7a9f1b5 Don't unnecessarily reevaluate tethering provisioning
Registering for carrier config changes can deliver a sticky broadcast
and can cause Tethering to think something has changed and reevaluate
provisioning status, even though this has been checked before it
entered tethering mode alive state.

Additionally, move the provisioning_app{,no_ui} resources into the
TetheringConfiguration, if for no other reason than now we can log
it in .toString().

82485a2660 Check mOwnedByTransform to avoid DELSA on SPI
The owned by transform flag prevents the removal
of an SPI from accidentally deleting an associated
SA in the kernel. That flag wasn't actually being
checked, so deleting an SPI would result in the
transform being removed.

The existing code already guarantees that the SA is
deleted when the transform is deleted
